TruFocal glasses with a nosepiece slider can help people who just can't adjust to wearing regular bifocals or progressive lenses. The slider allows the wearer to adjust the glasses' focus so there is no need for muli-focal lenses that create lines or disorienting visual transitions.

Trend Hunter previously reported on Josh Silver’s Adaptive Eyewear that uses water to regulate focus in third world countries, but Stephen Kurtin's TrueFocal glasses use a combination fixed prescription lens and a liquid-filled adjustable lens. They are available online for about $900.
